SHAVER AND HAIR REMOVER Filed April 20, 1937 Gus fay Bin/9495072ATTORNEY Patented June 14, 1938 UNITED STATES PATENT OFFICE 9 Claims.

The invention relates to a shaver and hair remover and more especiallyto a safety razor.

The primary object of the invention is the provision of a razor of thischaracter, wherein interfitted relatively movable cylinders providedwith slots when in motion will sever hairs for 1 shaving and hairremoving purposes, the cylinders being rotatable reversely to each otherin their interfitted relationship and also the innermost cylinder isreciprocatory and in this manner assures the positive shaving and hairremoving operation in the use of the razor.

Another object of the invention is the provision of a razor of thischaracter, wherein the same is roller acting so that it can be rolledover the skin for shaving and hair removing purposes and will not cutthe skin during the use thereof and thus assuring safety against injurywhile in use.

A further object of the invention is the provision of a razor of thischaracter, which is simple in its construction, thoroughly reliable andeffective in operation, readily and easily handled,

positive in the working thereof, absolutely safe from cutting the skinduring shaving or the act of removing hair from the human body, andinexpensive to manufacture.

With these and other objects in view, the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described, illustrated in the accompanyingdrawing, which discloses the preferred embodiment of the invention andpointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is an end elevation of a razor constructed in accordance withthe invention.

Figure 2 is an enlarged plan view partly in section.

Figure 3 is a sectional view taken on the line 3-3 of Figure 2 lookingin the direction of the arrows; and

Figure 4 is an end elevation of the innermost cylinder of the razor andremoved from the outer cylinder.

Similar reference characters indicate corresponding parts throughouttheseveral views in the drawing.

Referring to the drawing in detail, A designates generally the razorconstituting the present invention and comprises outer and innercylinders l0 and II, respectively, these being formedwithcircumferentially arranged elongated slots |2 adapted to register witheach other and such slots in each cylinder are disposed close to eachother so that when the said cylinders are rotated in opposite directionsin their interfltted relation to each other a shearing or cutting actionwill be set up for shaving and hair removing purposes.

The outer cylinder III, which functions as a roller in the use of therazor, is of greater length than the inner cylinder H and has fitted inany suitable manner in opposite ends thereof, internal gears l3, whilethe opposite ends of the 10 inner cylinder II are formed with spokes I4extending radially from end hubs l5, these being provided with pinionsl6. Interposed between the gears l3 and the pinions l6 are idling gearsthese being enmeshed with the gears l3 and I pinions l6, respectively,so that the outer cylinder l0 under rolling contact with a surface willdrive the inner cylinder H and these cylinders will rotate reversely toeach other through the gear connections therebetween.

Bridging the outer cylinder I0 is a yoke frame I8 in which are removablycarried stud journals l9, these having the hubs l5 Journaled thereon.Centrally of the frame I8 is a handle 2|), being fixed thereto in anysuitable manner.

The gear lit in one end of the outer cylinder III has formed therewithan annular cam 2| coacting with an annular companion cam edge 22 at theend of the inner cylinder next thereto so that on relative rotarymovements of the cylinders l0 and II these will be reciprocated withrespect to each other. In other words, under the operation of the cams2| and 22, companion to each other the inner cylinder- U will bereciprocated within the outer cylinder Ill. The bear- 35 ing ends 23 ofthe frame l8 for the stud journals I8 are outstruck to afford aclearance for the reciprocatory movement of the inner cylinder thesestud journals l9 being slidably fitted in said bearing ends 23 inaddition to the rotatable flt- 40 ting thereof. The gear l3 at the otherend of the outer cylinder is formed with a retaining annulus 24 for theinner cylinder II and this annulus additionally constitutes a track forleaf springs 25 suitably fitted with the cylinder 45 the purpose of thesprings 25 being for holding the companion cams 2| and 22 in contactwith each other under reciprocation of the said inner cylinder ii andthe relative reverse rotation of the outer and inner cylinders withrespect to each other.

The idling gears H are separably journaled on the yoke frame It and arein meshing engagement with the gears l3 and the pinions I6.

Under rotation of the outer cylinder in by contact with a surface thesaid outer cylinder effects a driver for the inner cylinder ii andthrough the gearing connections between these cylinders one will rotatereversely to the other in the use of the razor.

The hair entering the slots in the cylinders l and II will be sheared orcut and there is no liability of the cutting of the skin during the useof the razor for shaving or hair removal.

The journals l9 are separably fastened in the hubs l of the innercylinder II in any suitable manner.

During relative rotation of the cylinders l0 and H a reciprocatoryaction of the inner cylinder II is set up within the said outer cylinder10 when the razor is in use so that in this manner cutting action takesplace in paths at right angles to each other.

The gears IS in opposite ends of the outer cylinder II are held fast inplace when within said cylinder in any suitable manner, it beingnecessary to remove one of the gears l3 when it is desired to extractthe inner cylinder from the outer cylinder and, of course, the frame I8is separated to allow for the separation of the said cylinders.

The spokes H support the inner cylinder II in conjunction with the hubsl5.

What is claimed is:

1. A razor of the character described comprising slotted interflttedrelatively rotatable cylinders, gearing connections between thecylinders for reversely rotating the same with respect to each other,and means active between the cylinders for imparting reciprocation ofone cylinder relative to the other.

2. A razor of the character described comprising slotted interfittedrelatively rotatable cylinders, gearing connections between thecylinders for reversely rotating the same with respect to each other,means active between the cylinders for imparting reciprocation of onecylinder relative to the other, and a frame rotatably supporting theinnermost cylinder.

3. A razor of the character described compris- Y ing slotted interflttedrelatively rotatable cylinders, gearing connections between thecylinders for reversely rotating the same with respect to each other,means active between the cylinders for imparting reciprocation of onecylinder relative to the other, a frame rotatably supporting theinnermost cylinder, and stud journals removably fitting the frame androtatably connecting the innermost cylinder thereto.

4. A razor of the character described comprising slotted inter-fittedrelatively rotatable cylinders, gearing connections between thecylinders for reversely rotating the same with respect to each other,means active between the cylinders for imparting reciprocation of onecylinder relative to the other, a frame rotatably supporting theinnermost cylinder, stud journals removably fitting the frame androtatably connecting the innermost cylinder thereto, and a grip mediallyof the said frame.

5. A razor of the character described comprising slotted interflttedrelatively rotatably cylinders, gearing connections between thecylinders for reversely rotating the same with respect to each other,means active between the cylinders for imparting reciprocation of onecylinder relative to the other, a frame rotatably supporting theinnermost cylinder, stud journals removably fitting the frame androtatably connecting the innermost cylinder thereto, a grip medially ofthe said frame, and means active between the cylinders for maintainingreciprocal relation thereof with respect to each other.

6. A razor comprising outer and inner cylinders, the latter beingrotatably fitted within the outer cylinder, said cylinders having slotsregistering with each other, internal gears in the outer cylinder,pinions axially connected with the inner cylinder, idling gears betweenthe said internal gears and the pinions and meshing therewith, a frame,and journals carried by the frame and rotatably supporting the innercylinder.
